| | | An Illuminating Look at the Critical Role of Lighting in Successful Vision Sensing. No matter how powerful or robust a sensor is, successfully meeting challenging vision applications relies heavily on matching the vision sensor with appropriate lighting. Lighting sources, geometry and techniques need to be optimized to the target's optical properties. While contrast is critical, target size, speed, working distance, topography, color, and likelihood of defects are among the other considerations. The choices in lighting optics, color filters, diffusers and focusing elements are as varied as the choices of light sources, which include LEDs, fluorescents, lasers, and incandescent halogens or xenons. Lighting is essential to any successful vision sensing system. Fortunately, Banner offers one of the industry's most extensive selection of lighting solutions for vision sensing, plus the knowledge, personnel and experience to create an integrated solution that delivers reliable performance at desired speeds. Banner's lighting selection and accessories provide single-source convenience and support for matching a sensor and illumination. For the most challenging applications, Banner engineers will work with your sample parts to design an integrated optimal solution. | | |
